RING-SPINNING AND DOUBLING FRAME.

SPECIFICATION forming part of Letters Patent No. 501,738, dated July 18, 1893. Application filed March 9, 1893. Serial No. 465,254. (No model.) Patented in England March 8,1884=.N0. 4,566.

' To all whom it may concern.-

Be it known that we, GEORGE SHEPHERD and HENRY MIDGLEY, subjects of the Queen of Great Britain, residing at Bacup, in the county of Lancaster, England, have invented certain new and useful Improvements in or Applicable to Ring-Spinning and Doubling Frames, (for which We have received-Letters Patent of Great Britain, No. 4,566, dated March 8, 1884;) and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to the means which are employed in ring-spinning frames and doubling-frames for the purpose of limiting the extent of what is known as the ballooning of the threads being spun or twisted in such frames, or preventing the yarns, while being spun or twisted, from coming into contact- With one another, and it consists in certain improved constructions and arrangements of mechanism for independently sup- 2 5 porting and actuating or moving up and down a separate rail, or the like, which is located adjacent to the ring-rail and carries the arrangement or device which maybe employed for limiting the said ballooning, or preventing the yarns from striking against one another.

In our application for United States patent filed March 9, 1893, Serial No. 465,252, we have described and claimed an improved antiballooning or yarnseparating arrangement 5 consisting of a separate thin metal plate or rail, of any convenient length, or extending the entire length of the side of a ring-spin.- ning or doubling frame if desired, this thin plate or rail being. located above the ring-rail and having formed therein a hole of sufficient size for each spindle, the holes being concentric with the spindles and rings, and a narrow groove or slit leading into each hole, at about a tangent to the circle of the hole, being formed in the plate or rail for the thread to pass through. As is indicated in the drawings forming a part of this specification, we may employ this arrangement in connection with the supporting and actuating. mechanism hereinafter presented, or in lieu of the former, we may employ equivalent anti-balloonin g or yarn-separating devices, that is to say, other arrangements having suitable known forms and arrangements of devices located besides the spindles in a position to operate by interfering with the tendency of the yarn-balloons to expand during the rotation of the spindles, such, for instance, as the known arrangements in which anti-balloon rings, wires, plates or other guards are mounted on a rail .Wherebythey are sustained in proper positions adjacent to or between the spindles. In reducing our invention to practice, we mount the anti-ballooning or yarn-separating arrangement on rods that will slide freely up 6 and down, and we actuate these rods by the improved and novel means which we presently shall proceed to describe. In the preferred embodiment of our invention we actuate the said rods by self-acting means whereby the anti-ballooning or yarn-separating arrangement is caused automatically to moveat the same time as the ring-rail and in thesame direction as the latter, but through a traverse which is less in extent than that of the ring- 7 rail, and at a speed different from thatof the ring-rail, the distance between the anti-ballooning or yarn-separating arrangement and the ring-rail beingreduced as they rise. Our inventionfirst will be fully-described with reference to the accompanyingxdrawings; and then will be particularly.pointedout and distinctly defined in the claims appended to this specification and forming a part hereof.

Asshownt-in Fig. 4, theifront-edge ofthe; plate or rail is formedwith-aseries of'rou'nd equivalent, by'various means; The arrangemen'tshown-in Fig. '7 may be employed. In-the latter figure, the rod h is shown connected at its end with a-nut 'L" mounted upona screwshaft't' held in suitable bearings-in the .end of the frame A, the said nut being prevented from revolvingwith the screw-shaft 'byapin 2' extending from it, which moves freely in a slot 1' in the railA orin-azpart carriedby-that rail. When the screw-shaft? is rotated by thehandwheel tithe nut t'fland consequently the r-plat-e-orra'il a or e'quivalent arrangement, will be adjusted into ranyzrequired position. The arrangement show-nin Fig. 7 maybe duplicated on the opposite sides of a frame-or the levers 72 on both sidesofa frame'may be .con-nected-withpn-e such arrangement.

In Figs. 1, 2a-nd 3, welhave'sh'own self-acting means whereby the levers h, h, mayzbe operated to move the plate or :rail a, or equiva- -lent arrangement, up anddown. At f is a shaft extending 'lengthwiseof the frame at one side thereof,-and connectedin usual manner wit-h the poker-s of the ring-rail. The drawings showFblocks or pulleys fzfixedon the: said shaft, and chains f each connected aton-e'end with-one of such'blocksor pulleys, and at the other end with a bar 6 having a socket-formed therein forthereception of the lowerend-ofaone of thepokers. At 6 is shown a-stop projecting below each bar b and intended-.to-arrest the :descent of thering rail when the latt'elyin being lowered ,by hand, has reached a position which is low enough to enable doffingto bereffected. the said shaftf is caused :to rock by suitable known-means, and thereby-the usual movementslo'f thetring-rail or coppi'ngrrail are 00- casioned.

'Theend of the l'everj' hasra-short length of chain j attached to itgthat passes partly arou nd a: pulley 3' f P661120 .turnron a stud j oiua brac-ketsecured to the railv'A The other end of the saidsh'ort chain 'is connected with the-rod or wire =1) on the same side of the frame, and thus, as the shaft f and cam j IIO In practice,

oscillate, the plate or rail a, or equivalent arrangement, will be moved up and down 'accordingly. When the shaft f is turned by hand, as it may be to lower the ring-rail to the position for doffing, the shape and arrangement of the camj permit of the plate or rail 0., or equivalent arrangement, being lowered also to the proper doffing position. Instead of the disk-cam j being employed, as shown, a drum-camj may be used, as shown in Figs. 9 and 10, the action of such cam being in a line with the shaft f, and when this latter form of cam is used the lever j will be changed in position accordingly, and the wire or rod b may be connected directly with the end of the said lever. The pulley j may be a pulley with three grooves, and the short lengths of jointed chain in each groove may be attached thereto, one chain 7' extending between the lever j and its groove, say the middle groove, another chain 9' extending from the lower groove to the wire or rod 6, and another j extending from the third groove to and arounda pulley j on the other side of the frame, where it is connected with the wire or rod b on the latter side. Thereby, the anti-ballooning or yarn-separatingarrangements on both sides of the frame may be simultaneously actuated from the same cam. Itjs obvious that instead of chains and pulleys levers may be used, and a shaft may be used to connect'the mechanism of one side of the frame with that on the other side, if desired.

Figs. 11 and 12 show one of the arrangements of levers and connections that may be employed as just mentioned, if desired. It is to be understood, however, that no particular form and arrangement of the levers and their connections is regarded by us as especially important. Fig. 11 is a plan view illustrating sufficient to make clear the modification intended to be represented therein. Fig. 12 is a partly sectional elevation of the parts which are shown in Fig. 11. At 7' 9' in these figures, are represented horizontal levers having their outer ends joined or connected to the wires or rods, h h and their inner ends connected by short rods or links, 7' j toa cross-piece or head, j", on a sliding rod, 7'1 that is joined by a short rod or link, j to the lever j, the latter being actuated bya drum-cam, j, on the shaft, f. Fig. 13 is a sectional elevation showing an arrangement in which a shaft is used to connect the mechanism on one side of the frame with that on the other side, if desired, as stated above. In this figure the levers, j, j, on opposite sides of the frame are madefast upon a rock-shaft,

7 one of the said levers being engaged and actuated by the drum-cam, j, on the shaft, f.

In place of lowering the plate or rail a, or its equivalent, in the arrangement shown in Figs. 1, 2 and 3, by turning shaft fby hand, the lowering and subsequent raising may be effected through the aid of a lengthening and shortening or releasing arrangement such as that shown in. detail in Fig. 8. In Figs. 1 and 8 the rod or connection b between the lever j and the arm 71 of the first lever 71. is shown formed with a slot 1) in an enlarged part thereof, the said slot having at one end thereof a notch or offset 12 in Which-fits normally the pin 17 on the said arm h By lifting the end ofthe wire or rod 1) the notch b is re leased from the pin b and the arm 71, is then allowed to turn until the pin reaches the end of the slot, so as to occasion the lowering of the plate or rail, or its equivalent. By moving the arm h to lift the plate or rail, or its equivalent, the notch b at the end of the slot will again catch upon the pin b Other known and equivalent lengthening and shortening, or releasing, arrangements may be used.

WVe do not lay broad claim herein to mounting the plate or rail, or its equivalent, on rods and operating the same by means whereby it is caused to move in unison with the ring-rail but at reduced speed, and through a traverse of diminished extent,'or totlie stop for determining the limit to which the ring-rail may descend when being lowered for doffing, for we have laid such claim in our application, for patent hereinbefore mentioned. Nor do we lay broad claim herein to operating the said rod and plate, or rail by means of an arm which engages with the said rod to actuate the same, and is provided with means formoving'it up and down, or any claim to providing the said arm with operating connections having lengthening and' shortcni'nglmeans, for such claim we have laid in our other application for patent for ring-spinning and doubling frames, filed March 9, 1893, Serial No..465,253.
